DERAILER.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed August 23, 1907. Serial No. 389.877.

T 0 all whom it may concern:

Be it known that I, MARTIN C. SLonER- BECK, citizen of the United States, residing at Marion, county of Grant, and State of Indiana, have invented certain new and useful Improvements in Derailers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a derailer, and particularly to a structure pivotally mounted adjacent to the track rail and adapted to be held in operative and inoperative relation thereto.

The invention has for an object to provide a novel and improved construction of the derailer block by which it is mounted to resist the end thrust caused by the car wheel against the same and is guided in its pivotal movement toward and from the track rail.

A further object of the invention is to provide a novel and improved construction of the operating lever for the derailer which permits the movement thereof in one direction by the flange of the car wheel and the automatic return to its opposite position.

Other and further objects and advantages of the invention will be hereinafter set forth and the novelfeatures thereof defined by the appended claims.

In the drawing :Figure 1 is a plan showing the derailer in position upon a rail Fig. 2 a similar view with the derailer out of position for operation. Fig. 3 is a vertical section, and Fig. 4 is a detail section on the line 4'-4, Fig. 1.

Like numerals refer to like parts in the several figures of the drawing.

The numeral 1 designates the derailer block which is mounted upon the base plate 2 secured to the ties or in any other desired manner adjacent to one rail of the track. This block is pivotally mounted at 4 and provided at its pivot end with a curved or recessed face 16 which is adapted to bear upon the curved face of the block 3 also pivotally mounted on the base plate. These parts are normally in contact and the strain is thereby relieved from the pivot bolt 4 of the block and placed upon the brace block 3.

The derailer is normally held in the position shown in Fig, 1 by means of the spring 6 which surrounds the rod 7, said rod being supported from the track rail 26, as shown at 11. The spring'6 extends between the shown in Figs. 1 and 2. This extension is also provided with a pin 17 upon which the operating rod 19 is pivotally mounted and secured in position by means of the key 18 extending from the pin. The free end of the derailer is provided with the downwardly curved face 13 adapted to rest upon the rail and having a depressed face 15 extending below the top of the rail to receive the wheel flange and guide it upwardly and laterally of the rail. This face 13 is provided with a groove or recess 12 which forms a finger 14 that normally rests upon the top of the rail and catches the face of the wheel as it rides upward upon the derailer.

The operating rod 19 is preferably disposed between the adjacent ties 25 and extends beneath one of the rails 26. The outer end thereof is provided with the slot 20 disposed upon a pin 21 carried at one end of the lever 23 which is pivoted at 22 to the bearing lug.30 secured in position upon one of the ties in any desired manner, for instance, by fasteningdevices 28. The free end of the lever 23 is provided with the holding weight 24 which may be adjusted thereon by means of the set screw 27, as shown in Fig. 3.

The operation of the invention will be apparent from the foregoing description, and it will be observed that in the movement of the car wheel from left to right, in Fig. 1 the flange thereof will force the derailer backward into the position shown in Fig. 2 until the car has passed the same when the de-- railer is automatically thrown into its initial position to prevent a car from running out of a switch track into which it has been placed. The construction of the derailer having a pivotal bearing upon the brace block is such as to prevent a longitudinal movement thereof while permitting the greatest facility in the pivotal movement and this movement is effectually guided by the slotted extension and bolt therein. The operating lever is adapted when thrown to the right, as shown in Fig. 3, to permit the inward movement of the derailer, as before described, but when thrown to the left holds the derailer block positively out of operative position to permit free movement of the cars on the rail. It will therefore be seen that the invention presents a simple, efficient and economically constructed form of derailer adapted for application to any form of rail.

Having described my invention and set forth its merits, what I claim and desire to secure by Letters Patent is 1. A derailer comprising a pivoted block having a curved bearing face at its end beyond the pivot thereof, and a bearing block having an oppositely curved face disposed to contact with the bearing face. I

2. A derailcr comprising a pivoted block, a bearing face at one end of said block, and a circular pivoted bearing adapted to contact with the face of said block.

3. In a derailer, a pivoted block having a derailing face at its free end, a rigidly mounted rod extending through said block, a spring surrounding said rod and bearing upon the outer face of the block, a stop plate carried by the rod at the outer end of said spring, and a protecting casing surrounding the spring and rod.

4. In a derailer, a derailing block pivotally mounted at one end and provided with a downwardly curved derailing face at its free end, aslotted lateral extension from said free end, a guide pin in said extension, a pin extended from said extension, and an operating rod pivotally connected to said pin.

5. In a derailer, a-derailing block pivotally mounted at one end and provided with a downwardly curved derailing face at its free end, a slotted lateral extension from said free end, a guide pin in said extension, a pin extended from said extension ,an operating rod pivotally connected to said pin, a bearing block disposed in contact with the pivoted end of the derailing block, and a spring for normally holding said block in contact with the rail.

6. In a derailer, a pivoted block provided with a derailing face at one end, a spring for normally forcing said block toward a rail, an operating rod extending from said block and provided with a slotted end, and a pivoted lever provided with a pin entering said slot.

7. In a der'ailer, a pivoted block provided with a derailing face at one end, a spring for normally forcing said block toward a rail, an operating rod extending from said block and and provided with a slotted end, a pivoted lever provided. with a pin entering said slot, a bearing lug having a horizontal pivot for said lever, and a holding weight carried by the free end of said lever.

8. A derailer comprising a block having a downwardly curved derailing face at one end and a depressed portion at one side of said face, a finger at the outer side of said block separated from said face by a recess, a pivot.

for the opposite end of said block, and a curved bearing face beyond said pivot.

In testimony whereof I affix my signature in presence of two witnesses.
